ASP.NET MVC : How to transfer more than one object to View method?

Question

我完成了 NerdDinner 教程，现在我正在玩一些项目。索引页显示所有即将举行的晚餐:

    public ActionResult Index()
    {
        var dinners = dinnerRepository.FindUpComingDinners().ToList();
        return View(dinners);
    }

在DinnerRepository类中，我有方法FindAllDinners，我想添加到上面所有晚餐的索引方法编号，如下所示:

    public ActionResult Index()
    {
        var dinners = dinnerRepository.FindUpComingDinners().ToList();
        var numberOfAllDinners = dinnerRepository.FindAllDinners().Count();
        return View(dinners, numberOfAllDinners);
    }

当然，这是行不通的。由于我对 OOP 还很陌生，所以我需要这方面的帮助。

谢谢，

创建 View 模型:

public class DinnerViewModel
{
    public List<Dinner> Dinners { get; set; }
    public int NumberOfAllDinners { get; set; }
}

public ActionResult Index()
{
    var dinners = dinnerRepository.FindUpComingDinners().ToList();
    var numberOfAllDinners = dinnerRepository.FindAllDinners().Count();
    return View(new DinnerViewModel { Dinners = dinners, NumberOfAllDinners = numberOfAllDinners } );
}
